Mnnntans (i. i. his. a subject or the King or Greece. residing at Los lingeles; in the county ot Lots Angeles and State of Calihirnia. haven-1- vented new and useful Improvements in Chrome lit-tillers for Printing Pie. which the following a specification.

This in ention relates to chr no rollers for printing p and has for ts object to provide certain improvements over 311* Patent lie. 1353.662 the general objects oi? which are the same for my present application.

ll lore specifically, the object of this invention is to provide novel. means whereby the upper inking disk will be rotated so as to evenly distribute the ink upon the rollers which could not be done satisfactorily by using astationary disk as in my torementioned patent.

Other objects and advantages will be seen and the invention readily understood from the following description of the accompanying drawings in which:

Fig. l is a sectional front elevation oi a Gordon press looking rearwardly from the front of the chase.

Fig. 2 is a side elevation of Fig. 1.

Fig. 3 is a plan View showing the lower disk and the frame and supporting plate for rotatably supporting the upper disk.

Fig. .1 is a bottom plan 011 the upper disk.

Fig. 5 is a View taken on line 5-5 of Fi 8.

Fly improved device is shown as incorporated in a Gordon or any other suitable type of press adapted to employ the same. The press comprises substantially a bed 1. with the usual pawl and ratchet mechanism adapted to be actuated by the roller carrier 3 pivotally mounted upon the bed 1 so as to engage a lever arm a for actuating the rotating mechanism of the disk 2.

The usual sets 01 rollers are shown at 5 and 6 yieldably carried by the roller carrier so as to properly function when rolled over the chase and inking disk. Like the construction in my torementioned patent, usual 50 roller tracks 7 are mounted so as to guide the rollers 6 upon the same and over the upper disk 8. As shown in the drawing, the disk 8 is supported upon arms 9 which are suitably supported upon the bed 1 and these drawn in a to v 1 and p 1 to which is tened the guide tracks (I The supports 11 can also prov positionin of an ink disk.

A suitable bearing support for the upper disk is provided as by haying a plate 12lastened upon the forwardly extending position of the arms 9 and an aperture 13 in said plate is'adapted to receive the downwardly projecting spindle 1a of the disk 8 and is suitably spaced. therefrom as by spacing washer 15 and this being held in position by any suitable means here shown as a nut 16 having threaded engagement with the spindle on the other side of the plate 12.

Means for rotating the upper disk are pro vided by having the, outer portion of the lower side of the disk notched as at 1?, to provide a ratchet, these notches forming a shoulder and a tapering side so that a pawl 18 will only have engagement with the disk 8 in one direction. The pawl 18 is shown as pivotally mounted upon a support 19 suitably fastened to the members 11. A retractile spring 20 is fastened to the pawl 18 and member 11. so as to normally hold the same in rearward position which causes an actuating arm 21 extending from the pawl to be 'ard position and extending forwardly rroin the arm 21 is a roller engaging finger 22 adapted to actuate the pawl when the rollers 6 are passed up over the plate 8. The rollers 6 have outer guide 95 wheels 28 adapted to roll upon the t 'ack 7 and it is one of these wheels that engages the finger 22.

in the operation the rollers will pass up onto the upper plate and hold the same against rotation and continual movement of the rollers will cause engagement with the finger 22 which will allow the pawl to slip back and engage a forward notch. then when the rollers are passed oit the disk the spring 20 will pull the pawl so as to rotate the disk but it will thus be seen that successive operations of the rollers will cause suitable supports for 'oun'tain tor the upper complete iotetion; oi the rlisl: and thereby insuring even CllSlTl lllilGil of ink upon the rollers.
